Data on levels of inclusion and correlations between the activities of P/ sup 32/ in the eye tissue of rabbits at different periods during two months after a single introduction of the isotope are presented. Experiments were staged on 21 rabbits (42 eyes). P/sup 32/ was introduced subcutaneously in a concentration of 250 C/kg. Distribution of the isotope was studied with the radiometric method. The content of the activity in the eye tissues was calculated in mu C and in percentage relation to the total activity of the eyeball The initial quantity of the isotope in the eye tissues in percentage relation to the originally introduced amount was also calculated, as well as the content of activity in the tissues per 1 g of humid weight in mu C. In single subcutaneous introduction of P/sup 32/ it penetrates into all tissues of the rabbit eye. The eyeball recieves a total of 0.01%, of the activity introduced. On the first day the greatest concentration of activity is seen in the eye tissues with a rich vascular network, where intensive metabolic processes take place. The share of the crystalline lens in the included P/sup 32/ is negligible. Later on the named tissues rapidly eliminated P/sup 32/, whereas in the crystalline lens it is only on the 6th day that the maximum activity sets on. In a month and later about 50% of the activity preserved in the eye is concentrated in the crystalline lens. The most radiosensitive sections of the crystalline lens mainly accumulate P/sup 32/.
